Anyone know what the right hose/tubing is to use for the vacuum actuators on the heater box and where to get them? Are they 1/4" diameter? How long are they? The person that initially removed my heater box cut them so I don't know the length of any of them. Does anyone know of the place that makes reproductions or do I have to try and find aftermarkets (one of the ones on the heater box appears to be black and orange)? I've checked sites like Vintage Air, Classic Air, Old Air Products, etc with little to no success.
